Cassell Brothers Heating & Cooling has experienced rapid growth since we opened for business in 2008. Today, you can enjoy the benefits of our quality HVAC products and services all over the greater Columbia region. Whether you own a home in Columbia or operate a business, your indoor comfort depends on top-notch HVAC systems.
Did you know the average lifespan of a home air conditioner or heat pump is 12-15 years? If your unit is approaching or has exceeded this time frame, you are likely considering a new HVAC system. Learn how we can help you save with our rebates and special offers. To protect you from surprise breakdowns and costly repairs, we provide a comprehensive maintenance package backed up by both parts & labor warranties.
Keeping your home cool is our top priority. Having a properly functioning air conditioner not only cools down your space, it also helps control humidity and improve air quality. Having a reliable, well-maintained air conditioner can mean the difference between expensive, unexpected, and inconvenient repairs or breakdowns and comfort during the heat.
Air handlers are used to effectively circulate warm and cool air. Whether you're looking for a new installation, a repair to your existing unit, or a routine maintenance check, we've got you covered with professional services from our licensed and insured technicians.

If your system is broken beyond repair or you are looking to upgrade to a new unit, our Trane Comfort Specialist will help you choose from a range of high-quality options to determine which new system is the best fit.Whether you need a seasonal tune-up or not sure when your system was last checked, we can help.
Central air conditioning systems aren't suitable for every application, so if you need to air condition a specific space, consider the many advantages of installing a ductless mini-split system. We offer a full array of ductless air conditioning repair, installation and maintenance services. Our technicians are up-to-date on the latest products and service techniques.

We used the plumbing piece of Cassell Brothers to re-pipe the water lines in the attic and to replace two 50 gallon water heaters, also in the attic, with a tankless unit. We couldn’t be happier with the quality of the work performed. Those who did the job were professional and highly skilled. They were also extremely courteous and accommodated our needs. Special thanks to Steve and Josh for the excellent work!

I had a plumbing emergency on the day after Thanksgiving. I had family in from out of town and my downstairs bathroom was flooding out into the hall area. I called Cassell Brothers and although they were very busy, they were able to send someone out very quickly. Seth was friendly, professional, and knowledgeable. He quickly diagnosed and resolved the issue saving the day and putting our holiday back on track. What Cassell Brothers (or Seth) did not know is that one of my family members has recently been diagnosed and started treatment for stage 4 cancer. In fact, this is probably the last Thanksgiving

Great Service!
A/C went out over the weekend and I called Sunday evening. Kevin came out to look at my unit on Monday and Doug came by to price out a new unit for me on Monday evening.
Both were extremely professional and helpful the entire process. I appreciate Doug taking his time Monday evening to go over all of my options and pricing out a new unit for me.
Brian came on Wednesday morning to install my new unit. He and the guy assisting him were both professional, prompt, and did a great job ensuring my house was protected (foot coverings, drop cloths, etc.) They both were kind and courteous
